Dear all,

I met with a problem with Cisco 7911G ip phone.

the symptom is listed as follows,

1) when new call comes, there's no response both pick up or hang up the phone receiver.

2) when new call comes, there's no response when dial the soft key to answer.

3) when dial out numbers, there's no response both dial the soft key, or just pick up the telephone receiver.

4) other funcitons about the phone is ok.

5) we have about 2000 pieces of 7911G phones in using, about up to 30 phones have such kind of problem, and they went wrong one by one in every serveral weekes' duration. I tried to download software the phone by pressing #, plugging the cable, pressing 12345678980#, but this method doesn't work.

the CUCM server version is 4.3. and the status about the wrong phones is ok from the server.

I want to know what's the reason and how to deal with the problem....

Is there any one met with such kind of pecular problem?

thanks!!!
